One su04detects obstructions in one direction or in every direction?

Hi, one SU04 ultrasonic sensor obstructions in one direction, you can change the direction of the module by press the button on the sensor module.

What is the I2C address for this sensor?

The first slave address of SUI04 module is 0x71, each time you press the set button, the slave address will increase by 1. After you press the set button six times, the address will become 0x76. Then seventh press the set button will return to the address of 0x71. If you still can not understand this could contact us to get support!

Will this work with the Arduino microcontroller?

Hi, it cannot support Arduino microcontroller.
